December: Winter begins. Conditions in the Himalaya change from valley to valley and year to year, so treat this page as a planning guide, not a forecast. Check current conditions with your operator or the local forest or tourism office before you commit.
Weather and temperature
Cold and dry on the stable days. One Uttarakhand guide says December has less snow at lower altitudes, with routes usually still accessible, and calls late December the start of the best winter window.
Snow conditions
Sikkim is described as winter-hard in December, with Goechala advised against. Ladakh is in full winter with heavy snow.
Road access and transport disruptions
Snowfall can disrupt roads, especially higher up.
Daylight
The shortest days of the year. Plan to reach camp early.
Crowds
Late December is a holiday period and popular for Uttarakhand winter treks. We have not verified crowd numbers.
Difficulty considerations
Cold raises difficulty even where snow is thin. Nights can drop below freezing even when the days are sunny.
Beginner suitability
Easy snow-line treks in Uttarakhand suit beginners with an experienced operator.
